LAWSON FUSES L awson Fuses offer an exte n s i ve range of fuse-holder and fuse-link designs. L awson fuse-holders and fuse-banks are approved to major standards and designed to meet a wide range of applications: power distribution, motor protection, electronic, railway, shipping and street lighting. Two distinct designs of British Standard fuse-holders are available. The BOLTIN range accommodates bolted tag fuse-links to BS 88: Pa rt 2, in ratings of 20, 32, 63, 100, and 200 Am p s. The CLIPFIT range acco m m od ates co m p a ct dimensioned fuse-links to BS88: Part 6 and is available in ratings of 20, 32, and 63 Amps. Both ranges are available in a variety of colours and terminal configurations.
Both the BOLTIN and CLIPFIT fuse-holders are also available as f a ctory built fuse-bank assemblies. The fuse-banks co m p ri s e single-phase assemblies of busbar co n n e cted fuse-holders mounted on a back rail, for incorporation in distribution fuse panels. Lawson fuse-holders also include the well established ranges of PULLCAP and SLYDLOK products. The PULLCAP 240/415V a.c. modular fuse-holders incorporate Types MD and L cylindrical fuse-links to BS88: Part 1 and BS1361. The SLYDLOK range offers a wide variety of panel mounted applications. The range includes miniature fuse-holders for 5 x 20mm and 6.3 x 32mm fuse-links, compact fuse-holders rated up to 60 Amps at 240V a.c., and the W/X fuse-holder series, which accommodates either fuse-links or fuse-wire. Cylindrical fuse-holders are a ve r s atile option, o f fe ring fuse protection in four popular sizes up to a maximum fuse-link rating of 125 Amps. These fuse-holders accept cylindrical fuse-links to IEC60269 with principal dimensions of 8 x 31mm, 10 x 38mm, 14 x 51mm and 22 x 58mm.
